Photocatalytic filter module and air purifier including the same

Abstract

The present invention provides a photocatalytic filter module and an air purifier including a base frame in which at least one side is open, a plurality of support frames arranged to traverse the base frame, a plurality of light emitting units arranged on the support frame, and filter units installed in the base frame and disposed to be spaced apart from the light emitting units.

1 . A photocatalytic filter module comprising:
 a base frame in which at least one side is open;   a plurality of support frames arranged to traverse the base frame;   a plurality of light emitting units arranged on the support frame; and   filter units installed in the base frame and disposed to be spaced apart from the light emitting units.   
     
     
         2 . The photocatalytic filter module of  claim 1 , wherein when the light emitting unit emits light toward the filter units, the filter units are activated and sterilize a gas passing through the base frame. 
     
     
         3 . The photocatalytic filter module of  claim 1 , wherein the plurality of support frames are arranged to be spaced apart from each other and form an open area. 
     
     
         4 . The photocatalytic filter module of  claim 1 , wherein the plurality of light emitting units are arranged to be spaced apart along a longitudinal direction of the support frames. 
     
     
         5 . The photocatalytic filter module of  claim 1 , wherein the filter units are disposed above the support frames to be spaced apart therefrom and intersect with the support frames. 
     
     
         6 . The photocatalytic filter module of  claim 1 , wherein the filter units are disposed to be inclined with respect to the support frames. 
     
     
         7 . The photocatalytic filter module of  claim 6 , wherein an inclination angle of the filter units is set to be any one within a range of 15 degrees to 75 degrees. 
     
     
         8 . The photocatalytic filter module of  claim 1 , wherein a minimum distance from the filter units to the support frames is set to be any one within a range of 1 mm to 10 mm. 
     
     
         9 . The photocatalytic filter module of  claim 1 , wherein the light emitting units are disposed on both sides of the support frames, and
 wherein the filter units are disposed to be spaced apart from the both sides of the support frames to correspond to the light emitting units.   
     
     
         10 . The photocatalytic filter module of  claim 1 , wherein the filter units are formed to have a flat panel shape or to be at least partially curved. 
     
     
         11 . An air purifier comprising:
 a housing having an inlet and an outlet;   a photocatalytic filter module disposed in an internal space of the housing; and   a fan unit configured to discharge a gas which has passed through the photocatalytic filter module through the outlet,   wherein the photocatalytic filter module comprises:   a base frame in which at least one side is open;   a plurality of support frames arranged to traverse the base frame;   a plurality of light emitting units arranged on the support frame; and   filter units installed in the base frame and disposed to be spaced apart from the light emitting units.
